Designed for Full-Frame cameras, the Tokina AT-X 17-35mm F/4 give photographers a new wide-angle option.
With a focal length of 17mm at the wide side the lens yields a spectacular 103.9 degree field of view which
is great for shooting in tight situations or for taking in wide expanses of space.

This compact wide-angle zoom has a bright constant F/4 aperture make viewing and auto focus possible in
lower light situations but still maintaining a reasonable size and weight.

Two Super-Low Dispersion glass elements and one aspheric glass allow
the proprietary optical design to achieve excellent contrast and sharpness
as well as controlling chromatic aberration.

Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer
to switch between AF and MF simply by snapping the focus ring forward for AF
and back toward the lens mount for manual focusing. Additionally the mechanics
have been designed for better seals around moving parts making the lens more
water-resistant* than lenses of the past. The lens is also designed to stand
up to the rigors of daily use by photographers in a wide variety of shooting conditions and environments.

* The AT-X 17-35 is only water-resistant, not water-proof and is not designed
to be submerged or used unprotected in heavy rain.
